Tua has turned into a surgeon out there, even though he still doesn't have that much time to throw, even though there isn't much of a running threat, and even though he only has one WR who is better than average. He will only get better when those three things improve, which they will. His arm may get slightly stronger, but he won't ever have an arm that is better than the NFL average.
I think he has answered all the questions and Miami isn't going to look for another QB. Yes, we could probably get Watson, but that wouldn't be the best use of our NFL-best cap space. We should use that cap space to fix those three areas above and resign Gesicki. Draft a LB, RB, and OL with our first three picks, in some order. Pick up a starting caliber WR and top OL in free agency.
I know a lot of Miami fans love Gesicki. I like him, but I'd rather do a franchise tag with him and then trade him. Disappears more than I like.
I guess it depends what he costs. I don't think there is such a thing as a TE "disappearing", at least not in the sense that it is his fault, unless it is obvious he is just jogging his routes. Now, DL and LB can disappear, and that is a bad thing. But with a TD, it just means the offense is going elsewhere for reasons that are hard for us to determine as fans. Maybe he is drawing double coverage and freeing up space for others. Gesicki doesn't drop many passes and he plays with emotion. If we can sign him for five years at $70 million, I'd do that.
